Something strange is happening in World Editor. When I try to load a mission, only some missions appear in the list and not all of them.

The editor reads the mission paths from MissionPaths.txt found in the editor directory. It's some kind of bookmarks system intended to allow configuring mission favorites so you don't have to type in/copy-pasta the mission path everytime you want to load a mission. The stock file only contains a fraction of the available missions (mainly those I messed around with when testing various features of the editor), but you're free to add additional ones.

Thanks. I extracted the Missions from DataXtractor, but the folder is not showing up in Mafia Directory.
